摘要: Crystal monochromators can provide the exceptionally fine collimation requisite for study of small‐angle diffraction phenomena. To obtain sufficient intensity and contrast it is necessary not only to bend crystal but also use two crystals in tandem with their focal circles mutually orthogonal.The apparatus described uses x‐ray ``weak window'' line source illuminate (200) planes mica transmission (1011) a cylindrically ground, polished, etched quartz reflection. Symmetrical couple mounts were used minimize aberrations. The camera essentially isolates Kα1 component consequently reduces diffuse background general radiation artifacts as shown by pertinent applications collagen feather keratin. Although operating air using exposure times comparable (50–250 hr) those encountered aperture‐collimated systems, has resolved central first order 640‐A macroperiod fibers capable o...
